ALARM or EVENT PROBABLE CAUSE CORRECTIVE ACTION
“CHARGER FAULT” . Low floating voltage with the rectifier not
in current-limiting mode.
. Fuse F1 blown.
. Check the F1 fuse
Call the Customer Service
Department.
. Check the mains voltage and the
proper operation of the fans.
“HIGH BATT.VOLTS” The rectifier output voltage is higher than
the maximum allowable value.
Programmable threshold: default value or
customer demand value.
. Call the Customer Service
Department.
“LOW BATT.VOLTS” Battery in discharge resulting from:
. rectifier off.
. mains absence or low mains voltage.
. missing phase (TPRe).
Programmable threshold: default value or
customer demand value.
. Switch on the rectifier.
. Check the mains.
"HIGH DC VOLTAGE" The rectifier output voltage is higher than
the maximum allowable value.
Programmable threshold: default value or
customer demand value.
. Call the Customer Service
Department.
"LOW DC VOLTAGE" Low load voltage resulting from:
. rectifier off.
. mains absence or low mains voltage.
. missing phase (TPRe).
Programmable threshold: default value or
customer demand value.
. Switch on the rectifier.
. Check the mains.
“GROUND FAULT +”
Low resistance between positive output
and cabinet ground.
Programmable threshold: default value or
customer demand value.
. Check for the insulation fault.
“GROUND FAULT –“
Low resistance between negative output
and cabinet ground.
Programmable threshold: default value or
customer demand value.
. Check for the insulation fault.
"HIGH TEMPERATURE"
High temperature on the bridge. Detection
by thermo switch mounted on the heat
sink.
. Check the fan(s).
. Check if no obstacles are blocking
the airflow.
. Check the ambient temperature.
. Check the thermo switch.
